of thebearing, such shook is'taken up over the relatively broad bearing faces of the roller 16, and A1s sustained by two lines of thrust, the bevel 11 on the ring 10 to the ring 4, and from the bevel 12 on the ring 10 to the bevel 15 on the ring 5. Thus my` novel bearing affords a great lamount of weight and shock resistance, as

well as having tremendous load carrying ability, without increasing the friction or pressure within the bearings. This is due to the fact that substantiallyl every moving part of the bearing has a rolling contact, which, as is well known, presents the least resistance and friction. Each part of my novel bearing is designed and constructed to most 'eiiciently carry out the functions per. Also, by constructing my novel bearing with all rolling contacts, damage caused by heat is also reduced, and in fact is substantially eliminated, as my novel bearing constructed and arranged 'as above described, runs cool under all conditions. This, also, in practical use, is 'an important feature.

Referring now. to Fig. 6, I have therein illustrated a roller bearing utilizing a plurality of series of the separating rolls. In this Fig. 6 the outer concentric sleeve is comprised of a plurality of rings 30, 31, 32, 33 and'34, all

maintained in united and assembled position by an enclosing cap 35. An inner concentric sleeve is lcomposed of a plurality of rings 36, 37, 3 8, 39 and 40, which are likewise held inunited and assembled position by an enclosing cap 41. A double series of supporting rollers 42 and 43 are illustrated. The ring 38 has bevelled edges 44 and 45, and is so positioned that this ring projects between the rollers 42and 43 and the bevels 44 and 45 contact with the bevels 46 and 47, respectively. This ring 38, therefore, performs the functions of a guide for these rollers 42 and 43, also means to prevent longitudinal displacement of said rollers, as well as means to assist in taking up end thrust transmitted to the bearing, and performs the further function of assisting in absorbing shocks transmitted to the top of bottom of said bearing.

The outer rings 36 and 40 in the inner concentric sleeve have bevels 48 and 49 ,res ectively, which bear against the bevelled e ges 50 and 51 of the rollers 43 and 42 respectively,

these bevels-48 and 49 acting as guiding means, thrust sustaining means, and shock Separating rollers 52 and 53 are positioned between supporting rolls 42 and 43, in -similar manner to that illustrated in Figs. 1 and 2, these separating rollers having bevelled ribs 54 and 55, and bein contained within enclosing rings 56 and 57 all identically as described in Figs. 1 and 2. The rings 31 and 33 project into the grooves in the separating rollers similar to the ring 10 in Fig. 2, and these rings have -bevels. 58, 59, 60 and 61,

. and separating rolls 4assembled on said rings i bearing against the bevelsv 62, 63, 64, and 65 respectively. Thus rings 31 and 33 act as guiding means for the rollers 43 and 42, prevent longitudinal displacement of the same, preventdisalinelnent thereof, assist in sustaining end thrust, shocks, and the like, and the ring 38 serves as a guiding medium between the two rollers 42 and 43, further preventing disalinement and longitudinal displacement. Thesethree rings 31, 33 and 38, thus serve at all times to keep the component parts of the bearing in perfect alinement, increasing the efficiency of this form of the bearing, which-bearing pre-4 sents an extremely sturdy and rugged construction, capable oflong life and withstanding extreme shocks and blows, and necessi- Fig. 6, the 1ing s,30, 31 and 32 are first as. .sembled in the cap 35, one end of said cap The supporting rolls 43 53, rings 57, etc., are then l 30, 31 and 32. The rings 36 and 37, of the inner concentric sleeve, are then assembled in the cap 41, one end of said cap being closed. p The inner concentric sleeve as thusfar assembled is then inserted. Thereupon the ring 38 is inserted 'over the open end of the cap 41. Thereupon the rings 33, 34 and 39, with the supporting rollers 42, separating rollers 52, and rings 56, are then assembled as a lseparate unit and in-. serted into the thus far assembled bearing. Thereupon the ring 40 is inserted, and the open ends of the caps 35 and 41 turned down or closed, thus -firml clamping and uniting being turned over.

the bearing in assem )led position, and readyV in rings 74 are utilized. The outer sleeve 70 has a bevelled protruding edge 75 on which the bevelled edge 76 of the rollers 72 roll. A split. spring ring 77 is applied to-the outer sleeve in an appropriate peripheral groove, and said split ring is closely adjacent the bevelled edge 78 of the roller 72. T hus the supporting rollers 72 are held in the outer sleeve 70 jacent `supporting 'opposed bearing faces against longitudinal emplacement, by the bevelled protrusion 75 on one side and the split ring 7 7, on the other. The innersleeve has a bevelled protrusion or projection 79 against which the bevelled edge 78 of the rollers 72 bears. e Grooves 80 in the outer sleeve and 8l in the inner sleeve are provided, nierely to facilitate grinding of the surfaces 82 and 83 of the outer and inner surface respectively. Thus in this form of iny novel caring'` end .thrust is sustained from the bevel 79 on the inner sleeve to the bevel 75 on the outer sleeve through the entire etent of the rollers 72. Shocks or blowsare likewise sustained through the entire extent of the rollers 72, instead of, asin the .two forms above described, bein distributed throughout but a third 'of tie supporting rollers. While I have necessarily described my vpresent invention somewhat in detail, it will be appreciated that I may vary the size, shape, and arrangement of partswithin reasonable wide liinits without departing froin the spirit of the invention.` v

It will also be appreciated that the unit load on the bearing contacting faces is reduced at each point, due to the large number of bearingpoints and contacts provided in my novel bearings above described.

My invention is further described and defined in the form'of claims as follows :f-
